Part A Draw a mechanism for this reaction. Interactive 3D display mode o-CH Н,с. Н,с—о H3C CH3 Cн, Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where new bond should be created

4. A certain protein is known to be embedded within a cell membrane. What type of amino acids would you expect this protein to contain on its surface and why? 5. Structural proteins form the basis for hair and nails and have a high cysteine content. Cysteine side groups (-CH2SH) can react with each other to form disulfide bridge. What type of bonding holds the bridge together? Why is this interaction important for the function of structural proteins? Hemoglobin is...
